Además, analizamos los posibles orígenes de esta ictiofauna, postulando que parte de la cuenca del río Valdivia ha funcionado como un sumidero, principalmente su parte alta, con aportes de fuentes tanto costero-Pacífi cas como del Este de Los Andes. Concluimos que el río San Pedro es de particular valor ictiofaunístico por su alta riqueza específi ca, endemismos y características biogeográfi cas. PALABRAS CLAVE: Fauna íctica, Río San Pedro, Endemismos, Conservación, Chile. ABSTRACT Based on three consecutive years of sampling and bibliographic revision, the composition, singularity and conservation status of the San Pedro River ichthyofauna is described. In addition, the potential origin of this Valdivia River ichthyofauna was analyzed and this basin is proposed to have worked like a sink, mainly the higher zone, having been colonized both from Coastal-Pacifi c as from Eastern Andes sources. It is concluded that this river has a particular conservation value due to its high species richness, endemism and biogeographic characteristics. -

Its vast market is supplied from the wild population causing a significant environmental impact. In this study, we assess the effect of photoperiod on ovarian maturation in order to evaluate its potential as a tool to manipulate reproduction under artificial conditions. Four treatments in triplicate (light: dark, L: D) were tested: 24L: 0D, 12L: 12D, 0L: 24D and a progressive photoperiod corresponding to the daily photoperiod increments in wild during winter-spring transition, accelerated three times. -

SPECIES FROM THE TRICHOMYCTERUS (SILURIFORMES: TRICHOMYCTERIDAE) GENUS IN COLOMBIA Abstract The species checklist of the Trichomycterus genus, and its distribution by hydrographic systems in Colombia are presented. A total of 34 species were registered from which, six are found in subterranean ecosystems. The Magdalena river hydrographic system has the largest number of recorded species, while the Amazon and Catatumbo rivers records confirmed were not obtained. Key words: caves, diversity, species checklist, hydrographic systems, troglomorphic. INTRODUCCIÓN a familia Trichomycteridae está representada por 41 géneros y más de 241 especies descritas, posicionándola como uno de los grupos de Siluriformes Lmás ricos y ampliamente distribuidos en aguas continentales del neotrópico (CASTELLANOS-MORALES, 2010; FERRARIS Jr., 2007; RIZZATO et al., 2011). El género Trichomycterus Valenciennes 1832, es el más diverso dentro de la familia con aproximadamente 130 especies descritas y un número importante de nuevas especies descritas anualmente (ARDILA-RODRÍGUEZ, 2011a; ARDILA-RODRÍGUEZ, 2011b; CASTELLANOS-MORALES, 2010; FERRER & MALABARBA, 2011; RIZZATO et al., 2011; SARMENTO-SOARES et al., 2011). -
Presence of the Red Jollytail, Brachygalaxias Bullocki (Regan
Correa-Araneda et al. Revista Chilena de Historia Natural 2014, 87:20 http://www.revchilhistnat.com/content/87/1/20 SHORT REPORT Open Access Presence of the red jollytail, Brachygalaxias bullocki (Regan, 1908) (Galaxiformes: Galaxiidae), in freshwater forested wetlands from Chile Francisco Correa-Araneda1,2,3*, Patricio De Los Ríos2,3 and Evelyn Habit4 Abstract Background: Brachygalaxias bullocki (Regan, 1908) is a small-sized freshwater fish species (41 to 46 mm) and endemic to Chile. Its biology has still various knowledge gaps, and its distribution range has been reduced in the last decade due to human intervention. Findings: In this article, for the first time, its presence in forested wetlands of Chile (38°52′ to 39°02′ S) is documented. The presence of this species in these ecosystems is restricted to wetlands with permanent water regime and depths ranging from 15.7 to 83.5 cm. Conclusions: The physicochemical habitat conditions show important seasonal variations, suggesting that B. bullocki is resistant to a wide range of temperatures, as well as different levels of dissolved oxygen and conductivity. Keywords: Brachygalaxias bullocki; Fish fauna; Forested wetlands; Conservation Findings Consequently, B. bullocki changes in the past 26 years from Brachygalaxias bullocki (Regan, 1908) is an endemic, small- a vulnerable status of conservation (Glade 1988; Campos sized (41 to 46 mm) fish species (Stokell 1954; Cifuentes et al. 1998) to almost endanger (MMA 2014). Our goal is et al. 2012). It is endemic to Chile and still several know- to document, for the first time, the presence of this species ledge gaps about its biology exist (Habit and Victoriano in forested wetlands of Chile, providing more evidence on 2012). -

Fax: (57) 67462563; [email protected] Recibido 27-IV-2000. Corregido 9-X-2000. Aceptado 23-X-2000. Abstract: The trophic and reproductive ecology of catfish (Trichomycterus caliense and Astroblepus cyclopus) was studied in the Quindio River upper Basin, Alto Cauca, Colombia. The pH was neutral, water oxygen content high (8.4 ppm) and temperature in the habitats was 18.63 ºC; both species are nonmigratory and sympatric with four other fish species. The ovaries mature primarily between May and September in T. caliense; between Decem- ber and May in A. cyclopus. The mean size at maturity is 8.3 cm (standard length) in T. caliense and 6.0 cm (stan- dard length) in A. cyclopus; the sex ratio is 1:1 in T. caliense (X2=3.4, P≥0.05) and in A. cyclopus (X2=1.44, P≥0.1); the fecundity is low (191 and 113 oocytes respectively) and the eggs are small (1.5 and 2.39 mm respectively). The fishes are insectivorous and specialize in Coleoptera, Diptera and Trichoptera; Spearman Rank Correlation Coeffi- cients (rs=0.464) indicated that there are differences (T= 2.5148, P<0.01) between their diets; both taxa did not agree with the expected trophic habits for sympatric species that are morphologically similar and related in the sa- me trophic level. -

A New Species of Cave Catfish, Genus Trichomycterus (Siluriformes: Trichomycteridae), from the Magdalena River System, Cordillera Oriental, Colombia
Castellanos-Morales A new species of cave catfish, genus Trichomycterus (Siluriformes: Trichomycteridae), from the Magdalena River system, Cordillera Oriental, Colombia A new species of cave catfish, genusTrichomycterus (Siluriformes: Trichomycteridae), from the Magdalena River system, Cordillera Oriental, Colombia Una nueva especie de bagre de caverna, género Trichomycterus (Siluriformes: Trichomycteridae), del sistema río Magdalena, cordillera Oriental, Colombia César A. Castellanos-Morales Abstract A new species of troglomorphic catfish is described from de Gedania Cave, located in the middle Suárez River drainage, Magdalena River system, Colombia. The new species can be distinguished from its congeners by the combination of the following characters: reduction or loss of the cornea, reduction of eyes and skin pigmentation, very long nasal and maxillary barbels (maximum of 160% and 135% of HL, respectively), nine branched pectoral-fin rays, first unbranched ray of the pectoral fin prolonged as a long filament, reaching 80% of pectoral-fin length, anterior cranial fontanel connected with the posterior fontanel through an opening of variable length and width, first dorsal- fin pterygiophore inserted between neural spines of free vertebra 13-14 and free vertebrae 33-34. The presence of troglomorphisms such as regression of the eyes, reduction of skin pigmentation and long barbels suggest the troglobitic status of this species. A comparative analysis with other species of Trichomycterus from epigean and hypogean environments is presented.
